Problems solved by technology

Spilling liquids on a patient is undesirable.
Obviously, some thermal energy is lost when the thermal energy passes through the polymeric layer.
A problem with the rivet-like device is the liquid normally leaks.
Manufacturing a rivet containing thermoregulatory device has numerous quality control issues.
It is difficult to manufacture a thermoregulatory device with numerous apertures and each aperture being filled with a rivet-type device that does not leak.
As previously stated, a thermoregulatory device that leaks a liquid onto a patient is undesirable.

Embodiment Construction

[0020] The present invention is directed to a thermoregulatory device 10 interconnected to a fluid regulatory device 12 as illustrated in FIG. 1. The fluid regulatory device 12 provides a fluid having a predetermined temperature through a first conduit 13 to the thermoregulatory device 10. For this application, the fluid is a liquid and it is understood the fluid can also be a gas.

[0021] As illustrated in FIG. 2, the thermoregulatory device 10 has a first layer 102 and a second layer 104. The first layer 102 has a first interior surface 106 and a first exterior surface 108. The second layer 104 has a second interior surface 110 and a second exterior surface 112.

[0022] For this application, the first layer 102 contacts a patient. Since the first layer 102 contacts the patient, the first layer 102 has at least one aperture 105, preferably a plurality. If the fluid is a liquid, the liquid normally leaks from the apertures 105. To decrease leaking, a liquid-absorbing material 26 is po...

Abstract

The present invention is directed to a thermoregulatory device. The device has a first layer, a second layer, an enclosure, an inlet and a liquid absorbing material. The first layer has a first interior surface, and a first exterior surface. The second layer has a second interior surface and a second exterior surface. The enclosure is formed by sealing and / or attaching the first interior surface to the second interior surface. The inlet directs a liquid into the enclosure. The liquid absorbing material is positioned (a) at and / or near an aperture that allows a liquid to contact the liquid absorbing material; or (b) on the first exterior surface that is of a material that allows the liquid to contact the liquid absorbing material. In addition, the application is directed a method of using the thermoregulatory device to transfer the liquid's thermal energy from the enclosure to a patient's skin.

Description

FIELD OF THE INVENTION [0001] The present invention is directed to a thermoregulatory device. The thermoregulatory device is applied to a patient to alter the patient's temperature and / or maintain the patient's temperature. BACKGROUND OF THE INVENTION [0002] There are numerous types of thermoregulatory devices that alter and / or maintain a patient's temperature. One type of thermoregulatory device is Gaymar's T-pad device which has been existence since at least 1985. Gaymar's T-pad thermoregulatory device has a first polymeric layer and a second polymeric layer. The first polymeric layer has a first interior surface and a first exterior surface. Likewise, the second polymeric layer has a second interior surface and a second exterior surface. [0003] The perimeter of the first interior surface attaches and / or seals to the perimeter of the second interior surface to form an enclosure. The enclosure receives a fluid from a fluid regulatory device. An example of a fluid regulatory device ...
